Key-Based Model

A key-based (KB) model describes the major data structures, which support a wide business area. All entities and primary keys are included with sample attributes.

The objective of the KB model is to provide a broad business view of data structures and keys required to support the area. A KB model provides a context where detailed implementation level models can be constructed. The model covers the same scope as the Area ERD, but exposes more of the detail.
